Middle Atlantic NM Shallow Ext. BOX 2300 - 2348S/51-WH

Middle Atlantic 2348S/51-WH Shallow Non-Metallic Device Extension Box

Overview

The Middle Atlantic 2348S/51-WH is a shallow non-metallic device extension box designed to extend a standard wall box outward when a device — a keypad, control module, or low-voltage outlet — needs more depth or a flush surface to seat against finished wall material. At 4.88 in wide × 3.25 in tall × 1.13 in deep (12.4 × 8.3 × 2.9 cm), the 2348S/51-WH adds just over an inch of extension without creating a significant protrusion, keeping the finished installation clean in commercial corridors, offices, and structured wiring enclosures. The white finish suits drywall and light-colored surface environments where a painted or matching housing is required. TAA compliance makes this fitting suitable for federal and government facility installations where Trade Agreements Act sourcing is a contractual requirement.

Compatibility

The 2348S/51-WH is part of Middle Atlantic's non-metallic raceway and cord cover accessory line. It is designed to work with the 2300-series device box fittings within that system — specifically pairing with standard 2-gang device openings in the NM raceway family. Verify the specific raceway channel and base fitting dimensions before ordering: the 4.88 in width and 3.25 in height must match the device opening footprint of the intended raceway or box assembly. This fitting is not intended for metallic raceway systems or boxes requiring a grounded metal extension.

Installation Notes

The 1.13 in depth is the critical dimension — confirm the combined stack-up of the base box plus this extension does not exceed the available wall cavity or surface depth at the installation point. Non-metallic construction means no grounding continuity through the fitting itself; ensure the installed device does not require a grounded metallic enclosure per local electrical code. White finish is factory-applied; field painting is possible but not specified by the manufacturer for this fitting.
